Beware that the Si7021 can return a RH value < 0 or > 100, and Domoticz will not store it. Clamp the humidity to a valid range to avoid losing values.
Lately, my Sensebender reported values of 101-104 during the night. Took me some time to understand why Domoticz complained it didnt receive any values.
It received these values, but didnt like them.See section 5.1.1 of the Si7021 datasheet says:
Due to normal variations in RH accuracy of the device as described in Table 4, it is possible for the measured value of %RH to be slightly less than 0 when the actual RH level is close to or equal to 0. Similarly, the measured value of %RH may be slightly greater than 100 when the actual RH level is close to or equal to 100. This is expected behavior, and it is acceptable to limit the range of RH results to 0 to 100%RH in the host software by truncating values that are slightly outside of this range. -

Am I able to remote reboot the sensebender micro? I can send an OTA firmware if i manually press the reset button.
but can i use the reboot command in MYScontroller? it doesn't seem to do anything when issued. -
Is it the default dualoptiboot bootloader? Then the bootloader itself does not support OTA FW. You need to put a sketch on it, that supports OTA. (Default sensebender micro sketches doesn't)

yes it's the default bootloader. yes i have OTA added to the sketch. it works if i reset the device via manual reset. but what i'd like to do is send the reboot command from myscontroller. but it seems to do nothing ever. does the bootloader support reboot? or is that something i also have to add to the sketch?
situation: i have about 15 sensors all over the house. if i update, i'd like to be able to assign the firmware, and then issue the reboot command. so upon reboot, they take the assigned firmware. what i don't want to do is have to go to each one and manually press the reset button to get it to take the firmware. i'm sure it's healthier to run up and down 3 flights of stairs. but i'm lazy :)

Hi,
Three questions regarding SenseBender Micro:-
What board should I configure in Arduino IDE in order to upload sketches? Would it be equivalent to Arduino mini pro, or is there any "board library" to load ?(Didn't find it, Woudn't it make sense to be included in the examples/Libraries pack?)...
(Found it: https://github.com/mysensors/ArduinoBoards . If you look between the photos above there is a simple link lost in the between)
MySensors Admins: Just a small suggestion: As it is now, - a simple link between photos is easily overlooked. Can't you place it near the specs where it should be more visible? -
It has an I2C bus for the SI7021, but it seems the ATSHA204A (which I believe its I2C also) is connected to another pin (a3). Does this mean it has two I2C buses?
-
Can anyone confirm that the port that measures the battery voltage is A0?
Thanks,

For the battery powering voltage measuring do you mean that this is not needed after all? (https://www.mysensors.org/build/battery#measuring-and-reporting-battery-level)
It would be just a matter of enabling the flag "#define BATT_SENSOR 199 " and no resistors needed? -
Sorry for the dummy question, but my SenseBender Micros came with a small white sticker on top of the Si7021 sensor (like in the pictures above). Is it supposed to be removed or to stay like that?

Hello!
Help me understand why the sketches are not loaded in Sensebender Micro - there is a synchronization error:
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x82
....
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x82
avrdude: stk500_recv(): programmer is not responding-
FTDI connected via 3.3V jumper

Another device built on the SB Micro with SB bootloader is also not flashed with the same error, but on the PC of my friend, sketches successfully loaded into the device and on my PC are given the correct data when working sketch
-
device and serial port are selected correctly
-
mySensors Lib and device packs(AVR, SAMD) installed with standard lib and device managers(and also added path https://raw.githubusercontent.com/mysensors/ArduinoBoards/master/package_mysensors.org_index.json in the settings menu)
-
at the same time if I take a pure Pro Mini and load into it any sample sketch of mySensors package - it will successfully do it and will work.
What am I doing wrong and how do I get the Sensebender Micro to take sketches?
